A process is disclosed for producing silicone copolymers, wherein the process
comprises
the steps of:
- (a) providing at least one multi-stage blade-mixed plug flow reactor
having an entry and an exit;
- (b) continuously feeding (i) hydrogen siloxane, (ii) olefinically substituted
polyether or olefin capable of reacting with said hydrogen siloxane, and (iii)
catalyst for the reaction to the entry of the multi-stage blade-mixed plug flow
reactor, and
- (c) continuously withdrawing from the exit of the multi-stage blade-mixed
plug flow reactor a stream that comprises silicone copolymer and is substantially
free of unreacted hydrogen siloxane, provided that said hydrogen siloxane and said
polyether or olefin have a residence time at reaction temperature in the multi-stage
blade-mixed plug flow reactor sufficient to effect substantially complete hydrosilation.
